Or if someone can provide an xfs.ko, or point "pahole" at it yourself, and see if xfs_dir2_sf_hdr, xfs_dir2_sf_entry, and xfs_dir2_sf look more like http://sandeen.net/xfs-diskformat/xfs-oldabi-arm-pahole-structs or http://sandeen.net/xfs-diskformat/xfs-oldabi-fixed-arm-pahole-structs ? otherwise I will give this a whirl in the emulator again...
